The driver is installed and all, but I get no audio device.
I did passthrough both devices. The IGD itself and its HDMI audio device:
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)
00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06)
Any ideas?
